Palette Format Specification
This repository contains the specification for the Palette XML format, a simple format for representing colour palettes. The specification consists of a human-readable document and an XSD schema.

spec.md— The human-readable specificationpalette.xsd— The XSD schema for document validation
Overview
The Palette format is an XML vocabulary for representing a collection of named colours. Each colour entry carries a name and component values for red, green, blue, and opacity.
Namespace
The XML namespace for this format is:
http://markembling.info/xmlschema/colourchooser/palette/1
This namespace identifies version 1 of the format. A new namespace will be introduced only if a future version of the format introduces breaking changes. Backwards-compatible additions do not result in a new namespace.
Versioning
This specification follows Semantic Versioning:
- Major version increments correspond to breaking changes and introduce a new namespace.
- Minor version increments correspond to backwards-compatible additions to the format.
- Patch version increments correspond to corrections to the schema or specification documents where the format itself has not changed.
The current version is indicated by the version attribute on the root xs:schema
element of palette.xsd.
Git tags correspond directly to specification versions and are prefixed with v
(e.g. v1.0.0, v1.1.0).
